Quarterback Vince Young has been placed on injured reserve, and first-year guard Ryan Durand has been placed on waivers to clear room on the 53-man roster.
An eight-year veteran, Thornton (6-2, 233) has been on the shelf after undergoing surgery on his hip and shoulder in the off-season. Since signing with the Titans in 2006, Thornton has 366 tackles, 2 quarterback sacks, and 2 interceptions in 58 games.
Thornton dramatically reduced his base salary, going from $4.35 million to $1.6 million, to remain with the Titans for the final year of his five-year contract.
